PAPER SLIPPER.

Application filed July 20, 1923. Serial No. 652,689.

To all whom it may concern:

Be it known that we, SEBASTIAN KARRER and HUGH M. FRAMPTON, citizens of the United States, residing at Urbana, Illinois,

and 3821 Ashburton Ave, Baltimore, Maryland, respectively, have invented certain new and useful Improvements in Paper Slippers, of which the following is a specification.

This invention relates to new and useful improvements. in slippers generally, but more specifically to a slipper which is formed from a blank of sheet material.

The principal object of our invention is to provide a slipper which may be folded into compact form and which will consequently occupy but little space. Such slippers can be carried in a suit-case for ready use when travelling, occupying but little space therein, and avoiding the necessity of 2 carrying the ordinary non-foldable slippers.

Other uses for such slippers are readily apparent, such as, use by hotel guests, retail shoe store customers, etc.

Another object of our invention is to provide a foldable slipper of average size with yieldable fastening means whereby the slipper will automatically fit feet of different sizes.

A further object of our invention is to provide a foldable slipper which is extremely simple in construction and consequently cheap to manufacture.

With the above and other objects in View which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in which:

Fi l is a plan view of the slipper showing t e same in its folded or compact relation.

Fig. 2 is a plan View showing the side portions elevated and in a position to receive the foot.

Fig. 3 is a plan view of the blank, and

Fig. 4 is a cross-sectional view taken on the line 4--4 of Fig. 2.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

Referring to the accompanying drawings,

illustrated, the toe portions of the side por tions and also the heel portions of the side portions are not connected. The side portions are connected by fastening means preferably elastic, whereby a slipper of average size will readily conform to feet of different sizes. The fastening means is preferably located adjacent the toe portions of the sides and consequently the heel portions of the sides are caused to yieldably grip the heel of the user and thereby assist in retaining the slipper on the foot.

Specifically, our slipper is formed from a rectangular blank A of sheet mate-rial such as relatively stiff paper and it is scored substantially longitudinally along the lines 55 to form a centrally disposed sole portion 6 and two side portions 77, the latter being connected to the sole portion along opposite sides thereof. The scoring lines 5-5 preferably diverge from the heel por tion 8 of the sole to the toe portion 9 thereof so as to conform substantially to the outlines of the human foot. It will be noted that the side portions 77 are substantially co-extensive in length with the sole portion 6.

The side portions 77 are held together by a fastening means which we have indicated as a whole by the reference numeral 10. Specifically this fastening means consists of a pair of buttons 1111 respectively secured to the side portions 77 adjacent the toe end thereof, and a yieldable fastening means 12 such as an elastic band for instance, connects the buttons 11. We do not care to limit our invention to the use of yieldable fastening means, as non-elastic cords may be employed if so desired.

The heel portions of the side portions 7-7 are respectively cut away at 1313, the line of out being inclined from a point adjacent the sole portion 6. This cut away or beveled portion is located adjacent the narrow or heel portion 8 of the sole 6 and consequently this reduces the width of the heel end of each side ortion so as to permit the latter to be fol ed over onto the sole portion.

Furthermore. these cut away or beveled portions 13 cooperate with the sole portion t form an inlet for the foot as is rival-i shown in Fig. 2 of the drawings.

The toe portions of the side portions T-T and the sole portion 2) of the sole portion are respectively and conjointly formed with substantially V-shaped incisions 14-14 which form on the side portions 7--? resultant yieldable toe engaging portions 15-45. The side portions 7-7 are respectively disposed in overlapping relation against the sole portion 6 as shown in Fig. 1. In this compact form the slipper may be readily carried in suit-cases or the like and will occupy but very little space. The slipper is ready for instant use as all that is necessary to be done is to elevate the side portions 7-7 to the position shown in Figure 2. The yieldable fastening means 10 retain the side portions in abutting relat on so as to permit the foot to be readily inserted from the heel end of the slipper. After the foot is placed within the slipper, the heel end portions of the side portions will be caused to frictionally engage the foot adjacent the ankle, and the toe engaging portions 15-15 of said side portions will yieldably engage the toes of the foot. The elastic fastening means 10 permit the slipper to automatically adapt itself to feet of different sizes within reasonable limits.

Without further description it is thought that the many features and advantages of the invention will be readily apparent and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to Without departing from the spirit of the invention or scope of the appended claims.

We claim:

1. A foldable slipper comprising a single blank of sheet material folded longitudinal- 1y along straight lines to form a resultant sole portion and two side portions respectively connected to the opposite sides of said sole ortion, the entire side portions bein folda le over flat on the original lines 0 fold one on the other and against the sole portion.

A foldable slipper comprising a singleblank of sheet material folded longitudinall; to form a resultant sole portion and two side portions respectively connected to the opposite sides of said sole portion and being substantially co-extensive therewith, and releasable means fastening the toe portions of the side portions in overlapping relation, the heel (portions of said side portions being separate to permit the insertion of a foot. the entire side rtions bein foldable over fiat on the original lines of old one on the other and against the sole portion subsequent to the release of said fastening means.

3. A foldable slipper formed from a single blank of sheet material folded to form a resultant sole portion and two side por tions respectively connected to the opposite sides of said sole portion, and yieldable fas tening means connecting said side portions.

4. A foldable slipper formed from a single blank of sheet material folded to form a resultant sole ortion and two side portions, the lines of folds diverging from the heel to the toe, the heel portion of said blank being formed with forwardly extending incisions terminating at the respective folds to form resultant yieldable heel-gripping portions.

5. A foldable slipper formed from a single blank of sheet material folded to form a resultant sole portion and two side portions, the lines of folds diverging from the heel portion to the toe portion, and yieldablv fastening means connecting said side portions.

6. A foldable slipper formed from a sin- -gle blank of sheet material folded to form
